Larry, I've actually done that and made a soup out of a casserole serving! I would suggest taking that hamburger helper and adding in a small diced zucchini and/or chopped mushrooms, peppers, or maybe a bunch of spinach. They are very mild and lend well to tomato/Italian flavors.
I have a noodler that I bought off of amazon, but if you don't, you can use a peeler to make zucchini noodles
. I love spaghetti squash, but not as a replacement for pasta - it's too sweet. If I'm making a light alfredo (adobo, skim milk, and neufchatel cheese), or topping with marinara, I prefer zucchini. If I'm making spaghetti squash, I use it as I use other squash. I'm actually making it tomorrow with mushrooms and chopped tomato and a bit of white wine!
